## Did you know?

The metric system was invented in France in the years following the French Revolution, and a version of it is now used in most of the world to measure distance, weight, and volume. Basic metric units include the kilogram (the basic unit of weight), the liter (the basic unit of volume), and of course the meter (the basic unit of length—see below). Metric—or more often metrical—can also refer to the basic underlying rhythm of songs and poetry. So while the scientists' measurements are usually metric, the poets' are usually metrical.
